B
Answer to Question 2
Char data type is fixed-length, so that no matter the actual length of the data entered it will always take exactly the same storage space. For example, Char(10 ) indicates that 10 characters will always be stored for each value of that column. If the actual data entered is less than the specified fixed- length, the data will be padded with blanks. VarChar data type is variable length so that only the amount of space actually needed to store the data is used. Although VarChar may be more efficient in its use of space, it is not always preferred. VarChar requires the storage of some extra data to indicate the length of the data values, plus it requires some extra processing by the DBMS to arrange the variable length data. As another example, VarChar(10 ) indicates that the maximum length of a string to be stored in that field will be 10 characters. If the actual data are shorter, then fewer than 10 characters will be stored.
